Unused item! The white areas on the rubber are generally called "blooming" or "bloom phenomenon," which occurs when rubber compounding agents (especially fillers and vulcanizing agents) precipitate on the surface due to the passage of time or environmental changes. The blue areas on the rubber are thought to be due to a chemical reaction or aging. There is usually no major problem with normal use, but it may affect the impression depending on the condition. Please understand the above before purchasing.
